A molding material which contains a sinterable polymer and a wax as a binder and advantageously an ethylene/vinyl acetate copolymer, an organic peroxide, an azoester and an alcohol can be injection molded to give a molding, dewaxed without loss of dimensional stability of the molding and then sintered.

Molding material for processing sinterable polymers

A thermally expandable wax composition and its use in polymer-based actuators is disclosed and claimed. The compositions are wax-based and include conductive filler as well as a viscosity modifier to stabilize the composition against segregation. Optionally included are thermoxidative stabilizers.

Thermally expandable, viscosity modified wax compositions and method of

In a ceramic or powder metallurgical molding compound which contains waxes as binder, the addition of an ethylene-vinyl acetate copolymer, an organic peroxide, an azo ester and an alcohol in combination with an extraction with a solvent leads to an improvement in the dimensional stability and the dewaxing of injection-molded shaped parts.

Process and molding compound for producing inorganic sintered products

In a ceramic or powder-metallurgical molding composition which contains a wax as the binder, the addition of an epoxy resin leads to an improvement in the dry flexural strength and the workability in the green state of the shaped articles produced therefrom.

Molding composition for the production of inorganic sintered products

In a ceramic or powder-metallurgical molding composition which contains waxes as binders, the addition of an ethylene/vinyl acetate copolymer, optionally in combination with an organic peroxide and an azo ester and crosslinking of the binder, leads to an improvement in the dimensional stability and the dewaxing of injection-molded moldings.
